Abstract: A control method of a multipurpose rollable moving device may include monitoring the object docked at a docking portion, a docking portion and a driving device; identifying the object mounted on a mounting portion through an identifier element; determining whether or not a camera is mounted; determining whether or not a current mode is an object following mode when the camera is mounted; recognizing a following object when the current mode is the object following mode; determining a distance and a direction to the object; and executing a driving control and a posture control through the driving device depending on the distance and direction to the object.

Abstract: A multipurpose rollable moving device is provided. The multipurpose rollable moving device includes: a spherical driving wheel; a driving device that is installed within the driving wheel in order to apply a torque to the spherical driving wheel; a docking portion that is installed within the spherical driving wheel to generate a magnetic force; and a mounting portion that may be attached to a surface of the spherical driving wheel by a magnetic force of the docking portion and that may mount an article. Therefore, the multipurpose rollable moving device can mount an article and easily stably move in an omnidirection on the ground.
